Definitions

  • the invention concerns a device for loading the guide surfaces of bearing chocks supported in the housing windows of rolling stands with pressure plates that can be placed on the guide surfaces and that are loaded by hydraulic piston-cylinder units installed in the rolling stand housings.
  • Devices of this type are disclosed, for example, in EP 1 036 605 and EP 1 281 449, in which the hydraulic piston-cylinder units are installed in recesses of the rolling stand housing, and each cylinder-piston supports a pressure plate on its end face that faces the housing window and the given lateral guide surface of the bearing chocks.
  • This device makes it possible, by varying the hydraulic pressure loading of the piston, to produce well-defined contact forces and thus frictional forces on the bearing chocks while bridging the working clearance, i.e., to predetermine well-defined contact forces and frictional forces, independently of the rolling conditions.
  • the contact forces give rise to frictional forces, which have the same line of action as the rolling force. Even when the contact forces are held constant, there is no guarantee that the frictional forces also remain constant, because the coefficient of friction between the contact surfaces of the bearing chocks and the housing window changes due to the changes in the surface quality.
  • the surface of the contact surfaces becomes rougher due to corrosion, cooling water, or other abrasive substances.
  • the objective of the invention is to eliminate these disadvantages that impair the rolling process.
  • This objective is achieved by assigning pressure-measuring and position-measuring devices that can be controlled by automatic controlling devices to each hydraulic cylinder.
  • These automatic controls can operate in such a way that the piston maintains a predetermined position regardless of the force acting on it or in such a way that at a certain force acting on the piston, the piston is displaced and enters a different, specific position.
  • the automatic controls can also operate in such a way that the bearing chock is pressed against a fixed side of the housing window with a certain force. The displacement sensor then shows no further changes.
  • the position of the bearing chocks relative to a selected plane can be determined by the pressing and simultaneous measurement of the piston stroke made on the drive side and on the tending side of the rolls. If this position measurement is compared with previously stored position measurements, the wear on the housing windows and their mounting parts can be determined. If, as described, the piston is installed in such a way that two pistons are present per roll and they press against a fixed surface via the bearing chocks, the crossing of the rolls can be determined in this way. Evaluation of the measured values makes it possible to determine the position of all of the rolls relative to one another.
  • the rolls can be systematically crossed relative to one another by means of this position measurement.
  • the upper work roll and the upper backup roll can be set parallel to each other and crossed with respect to the lower work roll and the lower backup roll, which are themselves set parallel to each other. This crossing of the upper roll relative to the lower roll can then be used to influence the profile and flatness.
  • this integrated position measurement which measures directly in or on the moving members, the rolls can be exactly positioned.
  • FIG. 1 shows a schematic partial section through a rolling stand in a side view.
  • FIG. 2 shows the same type of partial section as FIG. 1 but through a different rolling stand.
  • FIG. 3 shows a control diagram
  • the bearing chock LS for the horizontal roll HW is supported in the housing window SF between the two housing posts ST 1 and ST 2 of a rolling stand.
  • a piston-cylinder unit which has a guide cylinder FZ and a piston K with a piston rod KS that moves in the cylinder.
  • a pressure plate DP is supported on the end face of the piston rod KS in the left housing post ST 1 .
  • the piston K and piston rod KS have a central recess AS, into which extends a displacement sensor WM, which is mounted on the outer rear wall of the guide cylinder FZ.
  • Hydraulic pressure lines HD which have a pressure-measuring device (not shown), open into the guide cylinder FZ on both sides of the piston K.
  • guide cylinders FZ 1 , FZ 2 , FZ 3 , FZ 4 , FZ 5 , FZ 6 , FZ 7 and FZ 8 which have the same design as the guide cylinder FZ in FIG. 1 , are installed on both sides of the rolls in both housing posts ST 1 and ST 2 .
  • All of these guide cylinders have a piston K, piston rod KS, and displacement sensor WM and can be pressure-controlled and position-controlled by means of pressure lines (not shown), which correspond to the pressure lines HD in FIG. 1 .
  • a clearance gap SP is provided between the pressure plates DP 1 , DP 2 and the bearing chock LS 1 and between the pressure plates DP 7 , DP 8 and the bearing chock LS 4 .
  • each cylinder is moved with a valve until it reaches the predetermined position set value. If the adjustable force limit is reached during this movement, the operation is interrupted.
